VAPORIZING APPARATUS.

Application filed February 25, 1916.

To all whom it may concern Be it known that I, ROBERT H. WILSON, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented new and use-- ful Improvements in Vaporizing Apparatus, of which the following is a specification.

This invention relates to improvements in vaporizing apparatus and has particular apv plication to apparatus for vaporizing gasolene and similar hydrocarbon fuels.

In carrying out the present invention, it is my purpose to provide vaporizing apparatus which will be found especially useful in connection with internal combustion engines and whereby the heat of the exhaust may be utilized to vaporize the gasolene or other hydrocarbon fuel and heat air to mix with. such vapor so that a warm mixture may be delivered to the engine cylinders.

It is also my purpose to provide apparatus of the class described whereby cold air may be commingled with the mixture of gasolene vapor and hot air so that the mixture may be properly proportioned and delivered to the engine cylinders at the right temperature so as to promote combustion.

Another object of my invention is the provision of apparatus of the type set forth whereby the gasolene and air may be delivered to the respective heating chambers under pressure and whereby the air may be taken from the apparatus in its original cool state so that the tires of a motor vehicle may be inflated and other apparatus operated.

A further object of my invention is the provision of heating and vaporizing appara- Y tus whereby the heated air may be delivered to radiators or heaters in the motor vehicle so as to heat the latter and whereby the gasolene vapor may be delivered to burners so that the vehicle may be illuminated.

A still further object of my invention is the provision of apparatus of the class set forth whereby the heated air may be delivered to the engine to maintain the proper temperature in the enginecylinders.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings; Figure 1 is a diagrammatic side elevation of heating and vaporizing apparatus constructed in accordance with the present invention. Fig. 2 is a vertical sectional view therethrough.

Serial No. 80,463.

Fig. 3 is an enlarged cross sectional view through the vaporizing and heating chambers on the line 3'3 of Fig. 2. Fig. 4 is a similar view on the line 4.4 of Fig. 2. Fig. 5 is an enlarged vertical sectional view through the throttle valve and associated valves. Fig. 6 is an enlarged sectional view through the pumps and operating mechanism therefor. Fig. 7 is a similar view taken at right angles to Fig. 6. Fig. 8 is a side elevation of the jacket for the engine cylinders. Figs. 9 and 10 are detail views.

Referring now to the drawings in detail, 1 designates an outer shell or casing and 2 indicates an inner shell arranged within the outer shell and spaced apart therefrom. The lower ends of the shells 1 and 2 may be closed by means of a plate 3, while arranged centrally of the inner shell 2 and having one end projecting through the plate 3 and the other end connected to the upper end of the shell 2 and opening into the space between the shells 1 and 2 is a vertical tube 4. Arranged within thetube 4: are heating tubes 5 spaced apart from the tubes 4 and disposed side by side and having the lower ends thereof opening into an exhaust pipe 5 se cured to the lower end of the tube 4 and projecting downwardly therefrom, and the upper ends projecting through an opening formed in the shell 1 in alinement with the tube 4 and into a pipe 4: connected to the shell 1 concentrically of the opening in the upper end thereof. The upper ends of the heating tubes 5 are connected to the bottom wall of a cup 4* that is secured in the pipe 4 and acts to prevent communication between the pipe at beyondthe tubes 5 and the space betweenthe shells 1 and 2, as clearly illustrated in Fig. 2 of the drawings. The pipe a may be connectedto the exhaust of an internal combustion engine so that the exhaust gases may be discharged through the pipe 4 and the heating tubes 5 and into the exhaust pipe 5'. Thus, the heat of the exhaust gases will radiate from the heating tubes 5 to heat the air surrounding such tubes, while the tubes will act as a mufiier to silence the exhaust of the gases from the engine. The chamberformed between the inner shell 2 and the tube 4 acts as a vaporizing chamber for gasolene, while the chamber between the shells 1 and 2 is an air chamber. In the present instance, the lower end of the tube 4: depends below the plate 8 and is formed with an annular series of air holes and rotatably mounted upon such end of the tube I as 1 is a valve 5 controlling the air holes and adjustable to vary the quantity of air flowing from the atmosphere into the tube 4. Thus, the temperature of the tube may be regulated; V "j, I u r Prejeaing through the plate 3 and into the vaporizing chamber are spray nozzles 6 connected by means of branch pipes 7 with oneend of a supply pipe 8. Connected with the inner shell 2 and in open communication with the vaporizing chamber and projectingthrough the air chamber and the outer" shell 4' is a gas conducting pipe 9 adapted to be connected to the inlet manifold, of the engine and located in the gas conducting pipe 9 is a throttle valve 10. In the present instance, the throttle valve 10 comprises a casing 11 andv a sleeve valve 12 rotatably mounted upon the casing 11 and having the outer surface thereof. formed with a cam 13. Leading from the throttle valve to the engineis a i e 13'. Connected to the outer shell 1 and in open communication with the airspace is an air tube 14: communicating with the pipe 9 between the throttle valve andthe" shell and located in the tube 14:- is a needle valve 15 under the control of the Gain 13 on thesleeve valve of the throttle valve Also connected to the gas? conducting pipe 9 in juxtaposition to the connection between such pipe and the air tube is an adjustable air valve 16 whereby air from the outer atmosphere may be draivn into the pipe 9 under the action of the gas passing through the pipe.

17 designates air air reservoir and 18 indlc'ates a gasolene tank and leading from thejairreservoir 17' is a pipe 19 connected 'journaled iirthe confronting ends of the piston rods of the pumps and a can 25. disposedbietween the rollers 24'and adaptedto act upon. the rollers alternately to slide the pistons. Theeiids of thefpiston rods 1 'equipped ivith the rollers are interconnected with each other by means ofa yoke 26 so that/both pistons will be lop'erated simultaneously by the cam. The; cam 2 5'is'mou11teduporione; end of a'shaft 27. and fixed upon "the other end of suchshaftis a friction disk and engagingoiie race of the friction 2 disk: 28 is a friction roller 29 mounted upon adrive shaft '30 and connected through the median of an arm 31 with a lever 32. The

drive shaft 30 is preferably formed of sections connected together by means of a uni- .versaljoint so that when the lever 32 is is moved in a direction at right angles to the first-mentioned movement, the roller 2!) may be drawn across the friction disk 28 to vary the speed of the pumps.

Located in the pipe 19 is safety valve 33, while connected in the supply pipe 8 is a regulating valve 34;. Also connected in the pipe 19 is a three-Way valve 35 and connected With the three-Way valve 35 is one end of an air hose 36, While secured to the other end of the air hose is a nozzle 37 adapted to be connected to tire valves or any other-apparatus.

In practice, the pumps 21 and 22 are set in operation and in the operation of the pump 21 air is drawn from the air reservoir 17 and forced into the air chamber, while in the operation of the pump 22 gasolene is drawn from the tank 18 and forced through the pipe 8 and branch pipes 7 and through the spray nozzles 6 into the vaporizing chamber. As the gas chamber and the air chamber are heated by the exhaust gases passing through the heating tubes 5, the gasolene sprays introduced into the vaporizing chamber are heated and vaporized, While the air in the air chamber is also heated. In the operation of the engine this heated gas from the vaporizing chamber is ll drawn through the pipe 9 and the throttle valve 10 into the engine cylinder and in the passage of the gas through the pipe 9, heated air is drawn from the air chamber through the tube 145 and into the pipe to commingle With the gas", While cold air from the outer atmosphere may be drawn through 7 the air valve 16 into the pipe- 9 to mix with the gas and heated air. The needle valve 15 is operated by the cam 13 on the throttle valve in the movements of the throttle valve to open and closed positions so that as the throttle valve is opened, the needle valve will be likewise operated to supply hot air in proper proportion to the gas. 16 is automatic in action and is adjustable so that the proper amount of cold air may be drawn into the pipe 9 to mix With the hot air and the gas and this mixture passes through the valve and into the engine cylin-' dersto furnish the explosive charges for the cylinders so that such charges may be ignite'd by the ignitingdevices' to drive the pis-' tons of the engine.

Tapped onto the supply pipe 8 and con I nected to the pipe 9 adjacent to the valve 16 is a gasolene pipe 38 whereby raw gasolene may be drawn through the throttle valve and mix with the air passing through the valve 16 and delivered to the engine The valve l cylinders to facilitate starting of the motor. This priming pipe 38 is provided with a cut off valve 39 whereby the priming pipe may be cut out of service after the engine has been started.

40 designates a gas receiver connected by means of a pipe line 41 with the gas conducting pipe 9 and located in the pipe line 41 is a cut out valve 42 and a regulating valve 43. By means of the gas tank and the pipe line 41 gas may be fed to the engine through the throttle valve to facilitate the starting of the engine. The gas will be found especially useful when the engine is cold and when drawn through the pipe 9 will mix with the air passing through the valve 16 to form a combustible mixture.

Tapped onto the air tube 14 is a hot air pipe 14 provided with a controlling valve 44 and this pipe 14' is adapted to connect with radiators or other heating devices located in the vehicle so that the latter may be heated.

Connected to the gas conducting pipe 9 is a branch pipe 45 equipped with a controlling valve 46. This pipe 45 is used to deliver gas to burners so that the vehicle may be illuminated, and is also connected to the pipe 41 by means of a branch pipe 45, as shown in Fig. 2 of the drawings, so that gas may be delivered from the vaporizing chamber to the tank 40.

The oil pump of the engine is indicated at 47 and this pump is preferably driven from the pump operating mechanism 23.

If desired, the air jacket 48 maybe employed and this jacket is adapted to inclose the engine and may be connected with the pipe 14 to supply hot air to the engine to maintain the temperature of the engine at the proper point. Or the jacket 48 may be connected with the inlet of the air chamber so that the air may be heated by the engine previous to the delivery of such air to the air chamber. In the latter event, the jacket 48 is provided with suitable dampers 49 to control the admission of air thereto.

From the foregoing description taken in connection with the accompanying drawings, the construction and mode of operation of my improved vaporizing and heating apparatus will be readily apparent.

It will be seen that I have provided vaporizing and heating apparatus which may be used in place of the usual carbureter and whereby the exhaust gases from the engine may be utilized to heat the gas and the air, while the heating tubes act as a muflier to silence the exhaust from the engine.

While I have herein shown and described the preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
